All four earned “Performance of the Night” honors in lieu of a “Fight of the Night” bonus and two performance bonuses.

UFC officials announced the winners at the night’s post-event news conference, which MMAjunkie attended.

Hall (12-5 MMA, 5-3 UFC) picked up the biggest upset of the night, and one of the biggest of the year, when he knocked out Gegard Mousasi (37-6-2 MMA, 4-3 UFC) early in the second round of their middleweight co-main event. Mousasi dominated Hall on the ground in the first round. But in the second, Hall threw a spinning back kick that drilled Mousasi in the face. He followed it up with a jumping knee to the chin, then pounced to finish the veteran with punches – giving “The Dreamcatcher” the first knockout loss of his lengthy career.

In the main event, Barnett (34-7 MMA, 6-2 UFC) picked up a fairly dominant decision win over Roy Nelson (20-12 MMA, 7-8 UFC). Fighting for the first time since December 2013, he got a 50-45 score from one judge and a pair of 48-47s to hand “TUF 10” winner Nelson his fifth loss in six fights.

Brandao (20-10 MMA, 6-3 UFC) needed just 28 seconds to finish off Katsunori Kikuno (23-8-2 MMA, 2-3 UFC) with a first-round TKO in their main-card featherweight fight. After the bout, the “TUF” winner said he’s eyeing a rematch with interim champion Conor McGregor, who stopped him in Dublin in July 2014.

Nakamura (31-6-2 MMA, 1-3 UFC) picked up a beautiful submission win over Li Jingliang (10-4 MMA, 2-2 UFC) to close out the preliminary card. Nakamura jumped on Jingliang’s back and secured a rear-naked choke, and before Jingliang could tap, he was unconscious and face-planting to the canvas with Nakamura still attached to him
